Thomas Uebel (Manchester) gives a talk at the MCMP workshop "Influences on the Aufbau" (1-3 July, 2013) titled "Neurath's Influence on Carnap's Aufbau". Abstract: In his very prompt review of Carnap’s Aufbau, Neurath was both highly appreciative of Car- nap’s achievements there and but also critical of some of its features. Neurath, of course, is reported to have been one of the readers of the typescript of an earlier version of that book that circulated amongst members of Schlick’s discussion group. This talk will consider the question whether Neurath had any in- fluence on the final version and what form this influence may have taken.
